Installation is easy, but I did have some issues when trying to get the pressure sensitivity to work using Windows XP and Paint Shop Pro. Being a USB plug-and-play tool it's such a pleasure to plug it into the front of my PC and leave it at that. Not messing with the wire jungle at the back of my computer. The drivers on the CD in the box were not the latest version, but after contacting Acecad and Divineo directly, both were quick to send us the updated version of the software. You can download the latest drivers HERE if you have any problems with the ones you get on the CD.
